4 stages sequencer
4seq - this sequencer has 4 stages with a forwards/backwards control allowing the development of quite complex sequences and patterns. It also gives CV outputs that are the reverse of each other, if outX is counting 1,2,3,4 then outY counts 4,3,2,1.
There are also gate outputs that are /2, /4, /8 & /16 divisions of the clock signal.
